A Cold Wednesday Evening Update

Good evening, folks. It’s another frigid evening unfolding across the bluegrass state, as we continue to settle into a bitterly cold setup. It’s a setup that can also bring some snow our way into the New Year’s weekend.

We are seeing the European Model trending more toward the GFS with the evolution of the weekend setup. Here it is for late Friday into Saturday…

It then tries to follow that up with our southern system by New Year’s Eve…

Just yesterday, that system didn’t really exist on the Euro.

The new GFS is in and ups the ante for snows from both systems. Here’s the late Friday into Saturday setup…

The New Year’s Eve system had been trending way south, but is just coming back by a smidge…

That’s still pretty disjointed, but it’s something to watch for. Given the arctic temps in place, any moisture would be maximized.

Bitterly cold air comes in and lasts through next week. There’s also a sharp dip in the jet stream showing by the middle of the week…

The sharper the trough, the better the chance of a bigger storm in the east.

We can worry about that later on, we have enough on our plate with the weekend setup.

I’ll see you guys back here tonight for the usual late night update. Make it a good one and take care.

Wednesday Afternoon Update

Good afternoon, everyone. It’s a frigid day out there, with a much colder pattern taking shape as we close out 2017 and begin 2018. It’s a pattern that will also throw some snows our way, starting with the weekend system.

Before we get to that, let’s give it up for the cold out there this morning. Lows were flirting with zero across the north, with lots of single digits showing up on the mesonet sites…

Wind chills were solidly below zero in many areas. Once again, this was a case of the lows being much colder than the computer models suggested.

A few areas of light snow and flurries continue across the southeast today, putting down light coatings in some areas.

Temps tonight hit the single digits again for many areas, with below zero wind chills showing up.

A streak or two of light snow and flurries will be possible later Thursday into Friday, with the main system showing up on Saturday. This will be a nice little system working in from the northwest…

Look for that to increase as we get closer. The snow ratios with that will likely be greater than 20-1, so it won’t take much moisture at all to put down a snowfall. Winds will also be very gusty and could reach 35mph as bitterly cold air crashes in.

The GFS is still trying to figure things out. It’s starting to show the Saturday system better, but it’s still a process…

The model still tries to pop that southern system close enough to bring snow in here on New Year’s Eve…

The bitter cold continues to look strong, strong, strong. Temps have a good chance to go below zero later this weekend into early next week. The Canadian continues to be on the extreme side…

Speaking of the Canadian, it is still trying to focus on a mid-week snow system coming out of the Gulf…

I will have the latest on WKYT-TV starting at 4pm and will have another update this evening. Make it a good one and take care.

A Bitterly Cold Pattern Settles In

Good Wednesday, everyone. Temps are in the tank out there today, and this is only the beginning of a bitterly cold period of weather across the region. As a matter of fact, this is a headline making winter pattern developing for much of the country.

In addition to the bitter cold, we have several snow chances to track, including the New Year’s weekend threat.

In the short-term, temps out there today start in the single digits in the north, with low and middle teens elsewhere. Wind chill readings will be below zero for several areas. Afternoon highs may not get out of the teens north, with low and middle 20s south. Those same gusty winds will make it feel much colder.

The weekend setup will feature bitterly cold air coming in here, and likely putting down some snow. The European Model is delayed tonight, so I didn’t get a chance to look at it before this update. Without seeing the European, it’s difficult to get too specific.

The Canadian Model is trending closer to what the Euro has been showing for several days now. It has a swath of arctic snows Friday night into Saturday…

Accumulating snows would show up with that, complete with 30mph or greater winds.

The GFS is coming around to that, with a stronger system than earlier runs showing up for Friday night…

The GFS still has a system coming behind it, but the cold is crushing it…

The bitter cold is impressive, with the Canadian Model going nuts later this weekend into early in the New Year…

That is VERY likely too extreme, but, if we just take add 10 degrees to those numbers, it’s still crazy.

The Canadian also is trending toward the European Model having more of a storm coming from the south a few days later…

Regardless, that’s another bitterly cold air mass coming behind that.

The GFS is wall to wall bitterly cold over the next 2 weeks…

For instance, this run of the GFS does never cracks the freezing mark in Lexington over the next 2 weeks. That’s impressive, my friends.

I will update things later today, so check back.

Have a great one and take care.
